The present invention discloses a special hydraulic press for bulging pressing forming of an automobile axle housing and a pressing forming method. A hydraulic press body is a closed frame consisting of an upper cross beam, a lower cross beam, four stand columns I, II, III, and IV, four vertical pull rods I, II, III, and IV, and four transverse pull rods I, II, III, and IV, and is used for balancing a deformation force up to 3000 T in the vertical direction or the horizontal direction in the pressing forming process. During pressing forming, the downward speeds of a main hydraulic cylinder, small left and right vertical hydraulic cylinders are precisely controlled to prevent the left end, the right end and the middle of the tube blank from bending.

In accordance with some aspects of the present disclosure, a method producing a composite board comprising plastic and cellulose is described. The method includes transmitting a first signal to a pair of opposing hot-platens, receipt of the first signal causing the pair of opposing hot-platens to compress and heat a composite mat; transmitting a second signal to the pair of opposing hot-platens, receipt of the second signal causing the pair of opposing hot-platens to heat and compress the composite mat at substantially a first pressure for a first time period; transmitting a third signal to the pair of opposing hot-platens, receipt of the third signal causing the pair of opposing hot-platens to release the composite mat from the first pressure; and transmitting a fourth signal to a pair of opposing cold-platens, receipt of the fourth signal causing the pair of opposing cold-platens to compress and cool the composite mat.

Compositions including a polyamide, and compaction rollers for an automated fiber placement machine incorporating the composition are provided. The polyamide may be a reaction product of at least one diamine and an aromatic dicarboxylic acid, a hydroxy benzoic acid, or their respective ester or acyl halide derivatives. The at least one diamine may include an amino terminated perfluorinated alkyl ether polymer or oligomer. The composition may have a thermal conductivity of from about 0.2 to about 50 Watts per meter Kelvin (Wm.sup.−1K.sup.−1).
