A new additive technique for manufacturing of short fibre-reinforced ultra-refractory ceramics is presented. This technique allows the fabrication of solvent-free, thin (~100 µm), flexible, and easy-to-handle sheets suitable for fabricating homogeneous or layered structures. A large range of compositions, in terms of matrix and fibre volumetric contents, from 0% to 100% is possible. The amount of short carbon fibres incorporated in the sheets ranged from 20 to 50 vol%, whereas the fibre length ranged from 3 to 5 mm. The matrix composition investigated with this technique consisted of ZrB 2 /SiC/Y 2 O 3 . By increasing the fibre amount from 35 to 50 vol%, an improvement of mechanical properties was observed. Four-point flexural strength (σ) ranged from 107 to 140 MPa, depending on the amount of carbon fibres (C f ). The same holds true for the work of fracture, ranging from 108 to 253 J/m 2 . Functionally graded composites were fabricated by overlapping sheets with a fibre gradient (0%-50%).

“…Recent research on the C/C composites of a primary objective in the fabrication of C/C composites is to increase the density within a shorter processing time, which means a reduction in processing costs. Therefore, studies on the manufacture of C/C composites by a single manufacturing process are in progress [12][13][14][15][16][17][18]. C/C composites use specific advanced applications including satellites and wing components, and missile engine.…”

“…Poor wetted fiber regions cause defects that promote premature failure of polymer composites. Therefore, in many instances, the use of short fibers is preferred [7]. The short fiber reinforced composites was used in wide spread application from bath tubs to interior structures in trains, cars, or even aircraft that manufactured using thermoplastic or thermoset resins as the matrix.…”

Abstract-the disposal of synthetic fiber is very difficult to be degraded and cause problems in the environment. The renewable materials have potency as an alternative material for replacing the synthetic material in the composite product. This study was to determine the critical fiber length of mendong fiber embedded in the epoxy composite. The methods were the extraction of mendong fiber from straw, pull out test methods, and morphology analysis of pull out a test using scanning electron microscope. Results show that mendong fiber had a shear strength of 11 MPa and indicated a critical fiber length of 630 µm. The low critical fiber length of mendong embedded in epoxy matrix indicate good adhesion properties of mendong in an epoxy matrix. It recommends that mendong fibers can apply as reinforcement in the epoxy composite in the form of short fiber.
